Magnet is one of the most common items in our daily life. It has a wide range of applications and can be used in industry, manufacturing, electronic products, etc. Magnets can be divided into two categories, namely permanent magnets and non-permanent magnets; permanent magnets can be natural magnetite or artificially made magnets. Among all permanent magnets, the strongest is the Neodymium magnet. This type of magnet is called the King of Magnets. Then how strong is it?
How Strong is the Neodymium magnet?
The magnetic energy product (BH)max of Neodymium magnets is more than 10 times that of Ferrite magnets, and it can suck substances more than 640 times their own weight. In our everyday life, the magnet’s magnetism usually does not harm humans, but if it is the most powerful magnet on earth, this is another matter.
In fact, the magnetic force of the Neodymium magnet has super lethality, and in order to verify how strong the magnetic force of the Neodymium magnets is, scientists did the following experiments:
The steps of the experiment are very simple. Just put two Neodymium magnets with opposite magnetic poles on both sides, place some objects in the middle of the two magnets, and then release the two magnets to test the strength of the magnetism.
First, they placed a can of Coca-Cola between two Neodymium magnets. The moment the Neodymium magnets were released, the can of Coke was instantly crushed by a powerful force, scattering the Coke all over the place.
After that, they also used an apple to do the experiment to test how strong Neodymium magnets can be. Unexpectedly, after the magnets were released, the apple was squeezed and deformed little by little under the magnetic force of the Neodymium magnets, and finally, the whole apple was crushed into dozens of pieces.
They explained that large Neodymium magnets can crush objects weighing several tons. Therefore, if the object used in this experiment is not an apple but a human’s body, then such a strong magnetic force of the Neodymium magnets will cause lethal harm to the human body, and even easily crush the human bones.
It can be seen from the above two experiments that the magnetic force of the Neodymium magnets is super strong. Thus, when using this kind of magnet, we must take extra care to prevent harm to ourselves due to improper use.
